CONNECTICUT, .A. CORPORATION OF CON- SEPARABLE FASTENER- Applioation filed January 19, 1923. Serial No. 613,718.

To all whom it may concern:

Be it known that I, CHARLEs M. RoBINsoN,

a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Separable Fasteners, of which the following is a full, clear, and exact description.

This invention relates to separable fasteners of the stud and socket type, and more particularly to fasteners such as that shown in my application filed June 19, 1922, Serial N 0. 569,223, allowed December 13, 1922, patented January 23, 1923, No. 1,443,277.

The object of the invention is to provide a socket member for separable fasteners of the type shown in my case above mentioned, in which the means for guiding the slidable resilient stud-engaging member of the fastener may be formed as a part of the back plate of the socket member and the studengaging member may be contained within a recess provided by embossing or cupping the face plate.

The invention consists in a socket member for separable fasteners, comprising a face plate, a back plate anda bodily slidable resilient stud-engaging member mounted therebetween, means being provided between said face and back plates for holding said stud-engaging member in predetermined relation thereto and for guiding said member during its sliding movement, as I will proceed now to explain and finally claim.

In the accompanying drawings illustratwhich like parts are similarly designated,

Figure 1 is a face view illustrating the fastener mounted upon a piece of material, such for example as a vehicle curtain, and showing the stud-engaging member in stud-engaging position. Fig. 2 is a view similar to Fig. 1 but showing the stud-engaging member in stud-releasing position. Fig. 3 is a back view of the fastener attached, as shown in Figs. 1 and 2, and showing the attaching washer and prongs. Fig. l is an elevation of the face plate detached. Fig. 5 is a plan view of the back plate with the stud-engaging member thereon. Fig. 6 is a perspective view of the back plate, and Fig. 7 is a central vertical section of same.

The fastener comprises a face plate 1, a back plate 2, and a slidable resilient stud- .engaging member 3 mounted therebetween.

t is an attaching washer.

The face plate 1 is embossed or cupped as shown to form a recess to contain the studengaging member 3 and is provided with a plurality of attaching prongs 5 adapted to pass through complemental slots 6 in the back plate 2, through the material towhich the socket member is to'be attached, and to be clinched upon the washer 4: in recesses 7 provided in the face thereof. The face plate is also provided with a plurality of y lugs 8 adapted to be passed through coma plemental slots 9 in the back plate and to be clinched upon the back of the back plate to assemble the face plate and back plate with the stud-engaging member 3 between them. i

The face plate, back plate and washer are provided with alined openings 10, 11 and 12,

respectively, through which the head of the stud X, shown in dotted lines in Fig. 1, may be entered, and the stud-engaging member 3 is so proportioned and so positioned between the face plate and back plate as to, intersect said openings for the purpose of engaging the neck Y of the stud as shown in Fig. 5.

The stud-engaging member 3 is formed preferably of resilient wire, and is provided with resilient legs 13 terminating in feet 141, the legs adjacent to the feet being bowed slightly toward each other to provide a slight contraction of the space between them to prevent accidental disengagement of the stud-engaging member from the stud. The

stud-engaging member is also provided with afinger piece 15 by which it may be withdrawn to the position shown in Fig. 2, for the purpose of releasing the stud.

For the purpose of properly positioning and guiding the stud-engaging member 3 with respect to the openings 10, 11 and 12, the back plate is formed with an integral boss 16 and a plurality of projections 17, forming guideways and a stop 18 for the legs of the stud-engaging member. The boss 16 is stamped up from the material of the back plate as shown particularly in Figs. 6 and 7, of such conformation as to form a guide straddled by and in engagement with the legs 13 of the stud-engaging member, and this boss is flanked by the projections or lugs 17 out out and turned up from the (lit material of the back plate to limit the spreading movement of the legs 13 when the socket member is pressed upon a stud to engage it therewith. Inward movement of the stud-engaging member is limited by means of a projection forming a stop 18 cut and turned up from the material of the back plate in the same manner as the lugs 17;

The face plate 1 is provided with openings 19 for the legs 13 of the studengaging member.

The operation is as follows :The socket member may be engaged with a stud by a simple snap action. As shown in Fig. l the socket member is placed over the stud with the stud alined with. the openings 16, 11 and 12 and then pressure is exerted upon the socket member so that the head of the stud will spread apart the legs 13 of the stud-engaging member and will snap past them, the legs thereafter returning to their normal position, as shown in Fig. 5. in engagement with the neck Y of the stud below the head thereof. When in this position, as hereinabove indicated, the slightly bowed portions of the legs adjacent to the feet 14. will prevent accidental sliding movement of the stud-engaging member, and conscquentl prevent disengagement of the stud'engaging member from the stud by such sliding movement. In order to disengage the socket member from the stud. it is mei el necessary to withdraw the stud-engaging member to the position shown in Fig. 2 by means of the finger piece 15 and lift the socket member off of the stud.

It will thus be seen that I provide a socket member for separable fasteners of a very simple, cheap and durable construction and, apart from the attaching washer 4:. which may be used or not as is seen fit. or for which some other form of washer may be substituted, comprises only three namely, a face plate, a back plate and a slidable resilient stud-engaging member mounted therebetween and held in pro lei operative relation by means of a guid boss, lugs and a stop formed integral w the back plate.

I have herein shown and described spe cifically the form and contruction of the parts of the socket member constituting this invention, but it is obvious that these parts may be of different conformation and arrangement from that shown and described without departing from the spirit of the invention or the scope of the following claims.

z fhat I claim is l. A socket member for separable fasteners, comprising a face plate, a back plate, a slidable resilient stud-engaging member mounted therebetween, a guide formed in tegral with said back plate for guiding said stud-engaging member, hi formed integral with said back plate for positioning -.id stud-engaging member, and a stop its formed integral with said back plate for limiting the inward movement of said studengaging member.

2. A socket member for separable fasteners, comprising a'face plate, a back plate, a stud-engaging member mounted therebetween and slidable with respect thereto, a boss formed on said back plate for guiding said stud-engaging member, and a stop and lugs for limiting the movement of said studengaging member.

3. A socket member for separable fats-- teners, comprising a face plate, a back plate, and a slidable resilient stud-engaging member arranged between said plates, said face plate being formed to provide a cavity to receive said stud-engaging member, and said back plate being formed integrally with means for guiding said stud-engaging i1111lher and other means for limiting its sliding and resilient movements.

A socket member for separable fasteners, comprising an apertured face plate, an apertured back plate, a slidable resilient stud-engaging member mounted therebetween and provided with legs intersecting said apertures, means for attaching said face plate to said back plate, means on sa d face plate for attaching the socket member to an article, and a boss, lugs and a stop formed integral with said back plate guiding said stud-engaging member and for limiting its sliding and resilient move In testimony whereof I have hereunto set my hand this 17th day of rlanuary D.
